Abstract

A system and method for maintaining an uninterrupted data flow in a communications network includes a transmitter (10), which transmits the data flow from a data source and a receiver (15); which receives the data flow. A channel (14) interconnects the transmitter (10) and the receiver (15); and communicates the dataflow between the transmitter (10) and the receiver (15). A switch (48) is located in the channel (14) between the transmitter (10) and the receiver (15). The switch (48) is openable for a period of time. which is sufficient to permit analysis of signal impairment in the channel (14) without interrupting the data flow.
